' tachment for disk plows, and has for its object to provide a device of the character specified, designed to steady the plow and hold it in the furrow especially when plowing in hard ground and when passing over rocks or other obstructions.

In the drawings, Figure 1 is a perspective view of the attachment in place looking from the rear, Fig. 2 is a top plan vlew of r the attachment detached, and Fig. 3 is a perspective view from the rear of the attach ment connected to a gang plow.

The present embodiment of the invention is shown in connection with a disk plow 1, of

ordinary construction, and the plow is pro- At its front endthe shank is provided with vided with an upright 1 at its rear end, the said upright being secured to the frame 1n any desired manner as indicated at 2, and preferably the upright is braced against the frame as shown at 3.

The attachment comprises a blade support 4, having at its front end an upwardly and forwardly extending shank 5. The support and blade are integral in present instance, and the blade is beveled on its lower side to form a cutting edge 6, as shown.

a loop 7, for engaging the upright, and the loop fits loosely over the upright as shown. The loop is formed in the present instance by doubling back a portion. of the shank upon itself and securing the said portion to the body of the shank in any desired manner, 1n

the present instance, by means of a pivot bolt 8. V v

A pair of anglebars is secured to the blade near its rear end, each bar consisting of a portion 9 and a portion 9 extending at ap-' proximately a right angle with respect to each other. The portions 9 are secured at their lower ends to the blade as indicated at 10, and from the blade the said portions di-' end of the shank by means of the bolt 8 before mentioned, the said plate extending slightly above the shank and for some little distance below as shown. Thus the attachment is suspended for free lateral swinging movement and also for vertical movement on the upright. It is entirely free from the disk plow with the exception of the loop 7 with the upright or standard.

The attachment is so arranged with respect to the plow that the lower edge of the blade moves in the furrow left by the outermost disk, that is, the disk remote from the plowed ground. If desired, a weight, indicated at 14 may be supported by the angle arms 9-9 and these arms are braced together in such manner that they will hold the weight. The weight let may be a stone or any other desired body having suflicient weight.

The device may also be used in connection with a gang plow, in which case it will be arranged as shown in Fig. 3. In either case however, the blade runs in the furrow, that is, adjacent to the unplowed ground. The blade and shank combined form a species of runner, and it will be noticed that the shank is at an obtuse angle with respect to the blade.

The plate 13 contacts at its lower end with the axle of the rear wheel of the plow, and holds the follower from leaving its proper course. It also prevents the plow from leaving its course when rocks and hard ground are encountered, holding the plow rigidly in position. In exceptionally hard ground the weight is used, while in ordinary ground it may be dispensed with. The plate 13 prevents both the follower and the plow from displacement, and even when the plow engages rocks, hard ground or like obstruction, the parts hold their relative position. The device which may be considered as a runner may be swung easily, in the construction of Fig. 1, to the left, but the swinging movement to the right is limited by the plate 13. It is obvious that the blade may be integral with the blade support, as shown in Fig. l, or it may be de- 15, is provided with the standard or upright 16 at its rear, in the same manner as shank 5 of Fig. 1, and the shank is pro-.

vided with a loop 21 for engaging the standard or upright 16. The angle bars 2222 are connected with the shank and the blade support in the same manner as the angle bars 9-9 are connected with the shank and the blade in Fig. 1. The portion 22 of each angle bar is connected to the shank by a bolt 23, and the portions 22 of the angle bars are connected to the blade support as indicated'at 24; Each angle bar is provided with an opening 25 at the junction of the portion, corresponding to the openings 12 of Fig. 1 and for the same purpose. The blade 18 is provided with open- .ings and the blade support 19 with registering openings for receiving bolts 26 for connecting the blade to the blade support."

The blade is provided with an angular portion 18 at its front end fitting against the shank, but the bolts 26 are engaged with the body of the blade. By removing the nuts of the bolts 26, the blade may be removed for resharpening or for repairs.

A beam 27 is secured to the frame of the plow, adjacent to the seat plate 28 of-the plow, and the said beam extends rearwardly and outwardly and is braced against the frame of the plow at the upright by an inclined brace 32. One end of the brace 32 is secured to the frame of the plow at the upright'by an angle plate 29, and the other end is secured to the beam.

A flexible member 30 as for instance, a chain, is arranged between the attachment and the rear end ofthe beam 27. One end of ,the chain is connected to the beam and the other end is connected to an opening in the adjacent angle bars 2222.

The operation of the construction shown in Fig. 3 is precisely the same as that shownin Fig. 4, but the attachment is however,

i wheel.

braced more firmly and more rigidly than in the construction of Fig. 1. The beam 27 and the inclined brace 32 together with the chainv -30 absolutely prevents swinging movement of the attachment toward the nected with the attachment shown in Fig. 3

in the same manner as with the attachment shown in Fig. 1.
